VEHICLE-WHEEL RIM.

Specification of Letters Patent.

Original application tiled June 10, 1912, Serial No., 702,857. Dividedand this application led November To all 'whom t may concern:

Be it known that I, JAMES H. WAGEN- Hons'r, a citizen of the UnitedStates, residing in the city of Akron, county of Summit, and State ofOhio, have invented certain new and useful Improvements in Vehicle-Wheel Rims, of which the following is a specification.

This invent-ion relates to tire-carrying rims for vehicle wheels, andparticularly to demountable'rims of the split type in which an endlesstire-retaining flange, mounted on said split rim, is retained againstlateral movement by an integral' Harige at one edge of said rim. *i

In my copending application filed June 10, 1912, Serial Numberv70257,patented March 28, 1916, No. 1,177,461', of which this is a division, Ihave described and claimed various features of invention not necessaryt0 be here described relating to the attaching of a demountabletire-carrying rim to a vehicle wheel by the use of a plurality of radialstuds adapted to force poitions of the rim away from the periphery ofthe wheel.

My present application relates to features of improvement adapted tofacilitate the detachment of a tire flange from a demountable rim,eitherof the class described or any type of tirecarrying lrim providedwith endless tire-retaining flanges seated thereon and held againstoutward or lateral displacement by a flange upon said rim base, andconsists informing a notcll in the base of the tirecarrying rimextending through the flange upon said rimbase, said notch being pref?erably located adjacent the point where the rim base' is split andpermitting the insertion of a suitable tool for disengaging the endlesstire-retaining'flange from said rim base.

In the accompanying drawings which form a .part of this Specification,Figure l is a plan view of a portion of the tire-carry ing rim showingthe transverse split therein and a notch'adjacent thereto; Fig. 2 is atransverse sectionthrough the rim and wheel felly, the position of thesection being indicated by the line II-II of Fig. l; Fig. 3 is atransverse section through a tire-carrying Serial N0. 63,154.

rim embodying a modified form of my invention shown in Fig. 4, andillustrating the sainemounted upon the felly of a wheel, the position ofthe section being indicated by the line III-III in Fig. 4:; Fig. l is aplan View of a portion of the tirecarrying rim of Fig. 3, showing therim at the point where the same is transversely split and illustratingin dotted lines one. end of the rim moved laterally to disengage theinterlocking means on the ends of the rim.

Referring to the drawings indetail, the numeral 1 designates a vehiclewheel felly, which, if made of wood, is preferably pro vided with ametallic felly band 2 permanently mounted thereon` 3 is a demountablerim carrying the tire 4. As shown in the drawings, the felly band 2 hasa raised flange 5 at one side thereof, the outer surface 6 of whichforms an annular convex bearing surface. The other side of the rim isbent down as indicated at 7, its outer surface `8 forming a secondannular convex bearing surface of less diameter than the convex annularbearing' Surface 6. The tire-carrying rim 3 is Split at and comprises abase or tire-seating portion l0 upon which also seat the endlessreversible tire-retaining flanges 11. The rim base is provided withflanges 12 preferably inwardly hooked, as shown, which retain theendless flanges 11 in position. The flanges 11 are preferably providedwith bases adapted to interlock beneath the inwardly hooked flanges 12.The rim base is provided with bearing surfaces 13 and 14 adapted toengage the bearing surfaces G and 8, respectively.

A notch l5 is formed in one side of the rim base to permit a tool to beinserted bcaway from the flange and forced radially inward and thenlaterally, as shown in Fig.

4, so that it may be grasped by the operator and collapsed, thuspermitting the flanges 1l and the tire to be taken off.

In Figs. 3 and 4 I have shown a modified form of demountable rim inwhich the tirecarrying rim has formed at one side thereof an integraltire-retaining flange, the otherof the latter opposite to that carryingthe endless tire-retainin flange, I preferably provide suitable loc ingmeans which, as shown, comprise a plate 16 secured to one end of therim, preferably upon the outside of the integraliiange thereof, thisplate overlapping a portion of the other end of the rim and havin one ormore holes 17 therein which receive pins 18 projecting from the otherend of the rim. When the ends of the rim are brought into alinernentthese pins enter the holes in the locking plate 1G and preventcircumferential separation of the ends of the rim. By moving the end ofthe rim carrying the locking plate laterally, however, as shown indotted lines in Fig. 4, the ends of the rim may be disengaged and therim collapsed sufiiciently to permit the endless flange 11 and the tireto be removed. The rim shown in these fig ures may be secured to thevehicle Wheel in any suitable manner.

I have shown herein Athe means disclosed in my companion case abovereferred to, comprising a plurality of radial studs 19 adapted to forceportions of the rim away from the felly band when other portions of therim are supported out of contact with the periphery of the Wheel by'adjustable studs, not here shown, thus causing the rim to seat upon thenon-adjustable studs 19 and also upon the periphery of the wheel betweensuch studs and the adjacent adjust able studs. 4

I claim 1. A tire-carrying rim for resilient tires comprising atransversely split rim base having an integral flange at the edgethereof, and an endless tire-retaining flange mounted on said rim baseand retained against lateral movement by said integral flange, said rimbase havin a notchfornied in one side thereof extending through saidintegral flange, said notch being located n'ear the point Where the rimbase is split and permitting the insertion of a tool for disengaging therim base from said endless tire-1 retaining flange.

2. A tire-carrying transversely split rim base for resilient tires, anda detachable tire-retaining flange mounted thereon and seating againstan integral portion thereof, said portion permitting the insertion of atool therethrough at the base of said tire-retaining Hange.

3. A transversely split tire-carrying rim having an inturned edgenotched to a point below the base of the rim.

4. A transversely split tire-carrying rim having a flanged edge notchedto a point below the base of the rim at a point adjacent the split. I

It is hereby certified that Letters Patent No. 1,201,121, grantedOctober 10, 1916, upon the a-ppliontion of James H. Wagenhorst, ofAkron, Ohie,'for an improvement in Vchi .lc-Whcel Rims, were erroneouslyissued to The United Rim Company, The B. F. Goodrich Company, TheGoodyear Tire 8; Rubber Company, and The United States Tiro Company,whereas snirl Letters Patent should have been issued to the inventor,said Wagenwrst and The B. l1. Goodrich Company, The Goody/ear TireRubber Company, and The United Stans Tir Company, jointly, SuidWegenherst being owner of onefifth interest in snid invention, as shownby the records of assignments in this oihco; end that. the seid LettersPatent should be rend with this correction therein that the same muyconform to the record of the ensei n the Patent Oe.
